Possibly the monitors EDID..
DPI is calculated from EDID if resolution is forced (& vice versa).
When you use the "DisplaySize" & the monitor has EDID, the reported DPI
is still used.
Need to add the following.
Option "UseEDIDDpi" "FALSE"
This could get messy if you have multiple displays & are not using
separate X screens.
Could use this to re-enable reported DPI (EDID) for specific monitor
Option "UseEdidDpi" "DFP-1"
